About me
I am researching in the domain of Natural Language Processing (NLP) for Software Engineering with focus on traceability link recovery and requirements engineering.
In my dissertation, I developed the automated traceability link recovery approach FTLR, that is able to relate requirements to their corresponding source code entities by utilizing fine-grained word embedding-based relations. Furthermore, I've developed the requirements classification approach NoRBERT and integrated its results as a filter into FTLR.
